There is a 4-cylinder, 4-stroke internal combustion engine with a stroke of 0.08m and a bore of 0.2m. there is a clearance volume that is 14% of the cylinder volume at bottom dead center. the crankshaft rotates at 2000rpm. the process in each cylinder is modeled as an air-standard otto cycle with a pressure p = 200kpa and temperature t = 400k at the start of compression. the max temp. in the cycle is is 3000k. now, answer the following questions: 1. draw the p-v diagram of the cycle and label the temperatures and pressures given. 2. how much heat (in kj/kg) is absorbed in each cycle of one cylinder? 3. how much heat (in kj/kg) is rejected in each cycle for one cylinder? 4. what is the net work (in kj/kg) delivered in each cycle of one cylinder? ignore changes in potential or kinetic energy. 5. what is the net work (in kj) produced in each cycle for 1 cylinder? 6. what is the net power (in horsepower) generated by this engine?
